Squoosh

Squoosh
Also known as: Vat's Incredible! Developer: Apollo Platform: Atari 2600 This game has uncompiled source code.

This game was never completed and/or given a public release. As a result of this, keep in mind that the developers might have used or deleted some of the content featured here, had the game actually reached store shelves.

To do: Document the earlier prototype.

Squoosh: In which a brave worker at the Apollo Grape Company risks his life to stomp giant grapes in a factory. Tragically, the Crash of '83 would prevent his near-death experiences from being finished or publicized for many years.

Not to be confused with the minigame from Putt-Putt Travels Through Time.
